I'm very fatalistic about tourneys where I get my money in good (anything greater than 2-1) and lose. I just move on.
The problem is at low levels (and at PartyPoker), you run into that in EVERY SnG because people push all the time, and eventually you'll get sucked out on. If I push and lose with KK vs. TT, I'll take those odds ALL DAY LONG, because I know I'm playing it right. Just like AQs vs. T8s. Sure, you'll lose 1/3 of the time, but most of the time, you'll bust him and get a big stack.
I've always had better luck in the $10-30 SnGs because good, solid, occasionally deceptive poker tends to be rewarded at those levels.
